`county of' Kings and State of New York,

have invented certain new and useful Iinprovements in Closures for J ars, Bottles, and other Receptacles, of which the followin is a specification.

e invention ertains more particularly,.

although' not exc usively, to closures of the screw cap type adapted for sauce and catsup and other receptacles. a

"We present our invention as embodied in a screw-cap comprising a threaded barrel portion and a non-rotary top portion having a depending central part bearing on its side a gasket, said depending portion and gasket being adapted to be forced in the mouth of the receptacle so that the'gasket may seal against the inner upper side walls of said mouth. 'l`he gasket preferably comprises a vertical band having a downwardly and inwardly tapered loweredge. Thetop portion of the closure extends outwardly from said depending portion'and is held within the top of the barrel portion by spring iingers out from said portion, and said barrel portion around its upper edges is bent downwardly and then flanged inwardly over the peripheral portions of the .top member of the closure whereby,.when the barrel por-v tion is screwed downwardly upon the neck of the bottle, said inwardly anged portion thereof rmly engages the upper outer portion of the. top and forces the depending member of said top downwardly into the,

mouth of the bottle with sealing eii'ect.

The invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying' drawings7 in which:

' Figure 1 is a central vertical section through a. portion of the neck of a bottle with the cap or closure of our invention applied thereto preparatory to bein'g screwed .downwardly upon said neck so as to seal the bottle;

Fig. 2 is a side elevation, partly broken away and partly in section, of the neckpf the bottle, with the cap of our invention screwed downwardly thereon and seallng the mouth thereof, the cap being shown in section; l

pending central portion 17 and a gasket 18 applied u on the exterior side of said portion' 17. he top .16 is of diskoutline and extends outwardly above the upper edges of the mouth of the bottle and seats against .said ed es when the cap is in operative position. he top 16 is held by the barrel portion 14, which portion 14 is vertically slit at a suitable number of points, say four, to form spring fingers 19, whose upperv ends are bent inwardly and given a reverse curvature, as at' 20, to engage the upper and lower edges of the peripheral portion of the top 16. The reverse curvature, at 20, of the upper ends of the fingers 19 form hooks to engage the top 16, and these hook portions 2O engage the top 16 firmly but with sufiicient freedom to permit the barrel portion 14; to be screwed downwardly upon the neck portion 16 without effecting the rotation of said top after' the latter has partly entered the mouth of the bottle. `The upper edges of the material of the barrel portion 14 are bent inwardly and downwardly forming a beading 21 and then inwardly to form a flange 22 which is directly upon the upper flat portion ofthe top 16 and serves to force the depending portion of said top into the mouth of the bottle when the barrel portion 14: is screwed downwardly to its operative position shown in Fig; 2. The material cut away from; the-upper portion of the barrel lfor the formatlon'of the spring fingers 19 results in 'there being formed in the beading 21/a number of recesses 28 which may be 4utilized to receive a blade or tool for aiding in the application of the cap to and its removal from the neck of a bottle.

The depending portion 17 of the top 16 is cylindrical and receives the gasket 18 which we regard as of special utility and which extends from the lower surface of the top 16 downwardly to about the lower edge of the depending portion 17. rlhe gasket 18 is acontinuous ring or band of rubber or other suitable packing material and has an inner dat wall engaging the wall of the depending portion 17, a Hat top edge to en-l gage the under surface of the top 16, an upper outer dat surface and a lower inwardl and downwardly beveled surface 24C. he upper inner edges of the lip of `the bottle are convex, and initially the gasket 18 projects outwardly over the inner upper edges of said mouth so that upon the application of the cap to the bottle the gasket becomes strongly pressed against the depending portion 17 of the cap, as will be understood on reference to Figs. 1 and 2. Thecompression of the gasket by the application of the capto the bottle results in the gasket sealing against the `facing surfacesofthe neck ofthe bottle and the depending portion 17 and in addition the upper edge of the gasket moves over upon the inner rounded edge of the'lip at the mouth of the bottle and thereby extends its sealing zone.

In the assembling of the parts of the closure the gasket 18 is applied upon the depending portion 17of the top member 16, and said top member is then forced u wardly into the barrel 111 until the periph eral edges of said top member become caught by the lhooks 20 at the upper ends of the lingers 19, the upper horizontal portion of said top member then being in engagement with the horizontal flange 22 formed on the barrel 1 4. `The cap or closure may then be applied tothe bottle, the barrel 14C bein screwed downwardly upon the bottle and forcing the descent of the top 16 and the entrance of the depending portion 17 and gasket 18 into the mouth of the bottle. The barrel ldmay rotate independently of the top 1.6, and hence said top with its gasket, when moving to sealing position, has .a direct vertical movement. 0n removing the cap or closure from the bottle the barrel 14 will be screwed in reverse direction and the hooks 20 will then force the top 16 and gasket 18 upwardly from the mouth of the bottle. As hereinbefore mentioned a knife blade or other instrument may be applied across the bottom 21, within opposing recesses 23, and utilized in screwing the barrel 14 downwardly or upwardly, as the case may be. 1n every instance the neck of the bottle must be proportionate with relation to the cap or closure so that when the cap is applied the gasket 18 may be enabled to create a proper seal.-

ln F ig. 6 we show a modification in the construction of the barrel portion of the cap, this modification omitting the beading 21 and recesses 23 of Fig. 1 and forming the spring iingers 19 from a barrel 14C having a closed top` 30, all the other features of construction being the same as those illustrated in Fig. 1.

ln both forms of the invention shown, the barrel portion of the cap has a substantial upper end to press the non-rotary top 16 downwardly into the mouth of the bottle, and in both form-s of the invention shown the top 16 is of the same construction as presented in Fig. 1 and has a direct downward movement into the mouth of the bottle and a direct upward movement therefrom, the barrel llrotating around said top 16 andserving to either depress the saine into the mouth of the bottle or lift said top therefrom. Y

The special form of gasket 18 shown as applied'upon the depending portion 17 of the top 16 is of special importance in theedectual sealing of the bottle in that by reason of the ta ered lower edge 24 of said gasket, a gas et of substantial thickness may be forced into the mouth of the bottle and efectually seal the same, as illustrated in Fig. 2, the tapered lower edge 24: of the gasket permitting the gasket to gain a proper entrance to the mouth of the bottle.

l/Vhat we claim as our invention and desire to secure by Letters-Patent, is:

1. A receptacle and a closure therefor comprising a barrel or skirt portion having a top member and inte al side fingers slit and bent inwardly an bend at their upper ends forming recessed hooks, a top having a de ending central part to enter the mouth of t e receptacle and a lateral flange extending outwardly from the upper end of said depending portion and engaged at its edges'by said hooks and at its upper surface by said top member, and a vertical gasket on said depending portion to seal against the same and the inner side walls about the mouth of the receptacle, said barrel yor skirt portion and said top being in independent parts and said barrel portion being rotatable around said top.

2. A receptacle and a closure therefor having a reverse v comprising a-barrel or skirt portion having 'upper end of said depending portion and engaged at its edges by said hooks and at its upper surface by said to member, and a vertical gasket on said (epending portion to seal against the same and the inner side walls about the mouth of the receptacle, said barrel or skirt portion and said top being in independent parts `and said barrel portion being rotatable around said top, and said receptacle and closure having interengaging portions for securing the closure on the receptacle.

3. A receptacle and a closure .therefor comprising a barrel or skirt. portion having a top member and integral side ingers slit and bent inwardly and having a reverse bend at their upper ends forming recessed hooks, a top having a depending central part to enter the mouth of the receptacle and a lateral flange extending outwardly from the upper end ot said depending portion and engaged at its edges by said hooks and at its upper surface by said top member, and a vertical gasket on said depending portion to seall against the same and the inner side walls about the mouth of the receptacle, said gasket having' a downwardly and inwardly tapered lower edge, a Wall to engage said depending portion of said top, a wall to engage the adjacent surfaces of 'the receptacle and an upper edge to engage the flange of said top, and said' barrel or skirt portion and said -top being in independent their upper ends forming recessed hooks and recesses inv said bead at the points where the upper ends of said ingers were out therefrom, a top having a depending'central part to enter the mouth of the receptacle and a lateral flange extending outwardly from 'the upper end of said vdepending portion and engaged at its edffes by said books and at its upper surface by said top member, and a vertical gasket on said depending portion -to seal against the same and the inner side walls about the mouth of the receptacle, said barrel or skirt portion and said top being in independent parts and said barrel portion beingrotatable around said top.
